In the past CNC Porting was used mostly for
Formula 1 and NASCAR.
We now offer CNC ported Heads for Dirtbikes and ATV's.

We took our best hand ported head and had it digitized the dimensions
for CNC replication. The CNC Machine does not make the porting
job better. The most important advantage of CNC porting is that it
duplicates the porting job exactly the same every time. Jobs that
are not done on CNC machine will be hand ported by "Luke".

Although the CNC machine is very efficient at machining the
ports quickly and exactly the same every time is is not very practical for polishing
work. The main advantage of polishing the combustion chamber and exhaust ports
are to prevent carbon build up. This step of the porting is still down by hand.
Intake ports are finished with a light grit sanding then glass bead blasted.
Flow testing has shown that Bead blasting does not decrease air flow but it
does help prevent "puddling of fuel" which is fuel droplets that can
form on a polished surface. See links below to read about this equipment and
its advantages.

here is a quote from www.stockcarracing.com "Until
just a few years ago, the Serdi was often seen as the state-of-the-art machine
and was most used by the top pro racing shops. These days, there is a new player
on the block when it comes to generating high-tech seat designs-the single-point-tool
